Ferro-alloys:
Non ferrous metals and scrap:
Medium carbon Ferromanganese, a ferroalloy with high content of manganese, is made by heating a mixture of the oxides MnO2 and Fe2O3, with carbon in a furnace. They undergo a thermal decomposition reaction. It is used as a deoxidizer for steel. Henry Bessemer invented the use of medium carbon ferro manganese as a method of introducing manganese in controlled proportions during the production of steel. The advantage of combining powdered iron oxide and manganese oxide together is the lower melting point of the combined alloy compared to pure manganese oxide. A North American standard specification is ASTM A99. The ten grades covered under this specification includes: standard ferro manganese , High-carbon ferro manganese, Medium-carbon ferro manganese, Low-carbon ferro manganese. A similar material is a pig iron with high content of manganese, is called spiegeleisen.
